We have purchased a AAA package for Feb. our agent told us she will be checking weekly for new discounts and if we find one to give her a call and she will have the new discount applied and see which ones saves us the most. ask your agent if they will do the same. She verified with Disney as long as we hadn't paid in full yet and it was further than 45 days out we could change to the "new discount" as long as it was still available
